Explanation of Terms:
Polythene comes in many different sizes and also can have various additives or properties. Polythene has changed a lot over the years! Below is an explanation of some of the terms used:
- Microns: This relates to the thickness of the polythene so for example:180microns x 4=720G, 200 mcns x 4 = 800G etc.. Reputable manufacturers or suppliers generally have this pre-printed on the polythene itself. It is also a good way of checking that you are getting the product that you ordered!
- Thermic: The polythene is treated so that the temperature 1-2 degrees warmer than the outside temperature.
- Anti-Drip or Anti-Fog: This reduces condensation and reduces the surface tension. Condensation evaporates or rolls off the film.
- Diffused: This polythene better controls the greenhouse climate, by reducing temperature fluctuations. Peak temperatures are lowered while minimum temperatures are not. Harmful UV radiation is shielded to prevent plant scorching.
